' Application filed May 10,

To all 'wlzom'c't may concern:

Be it known that I, HENRY B. GREENOUGH, a subject of the King of Great Britain, residing at Beverly,-in the county of Essex and State of Massachusetts, have invented certain Improvements in Applying Apparatus, of which the following description, in connection with theaccompanying draw.- ings, is a specification, like reference charactors on the drawings indicating like parts in the several figures.

My invention relates toapplying appa-. ratus, being especially adapted for the placing of paste or like adhesive substances upon such work as shoe parts.

The invention has as an object the provision of a simple, unitary apparatus for applying the substance from. a holder to work supported in a chosen one of'a plurality of positions, the particularposition in'which the application is made at any time depending uponvconditions under which the work is being done, as the type of machine to which the apparatus is an auxiliary, or the manner in which the machine operates. One advantageous utilization of-the invention is in connection with heelrattaching machines of the character of that disclosed in the application of Benjamin F. Mayo, filed June 3, 1918, Serial No. 237,951. This heeler is so designed that it may be arranged to drive the attaching nails in opposite directions, either up or down, and the work, as a toplift which is to be spanked upon the heel, is correspondingly oppositely positioned,,with the inner surface up in the first instance and down in the second. Upon this inner surface it is customary to place,-before attachment to the body of the heel is effected, a coating of paste to render the union more se cure. The apparatus of the present invention is adapted, withoutreorganization, to accomplish this pasting of the top-lifts in both relations and from a sinpply of the adhesive maintained in a constant position. For the attainment of such anobject, I-employ an applying member capable of movement from a sourcejof the substance to be applied in different directions for co-opera Preferably, there .is a movahlesupport for the applying member, together with means acting during the movement of the support'to' selectively determine the position of the applying member upon said support, as by re- Specification of Letters Patent.

versing it. Thus the applying member may travel into contact with a top-lift held above or below the heel to which it is to be attached. i i

In the accompanying drawing, illustrating one of the several embodiments which my invention may assume, I

Fig. 1 is a top plan View of my improved applying apparatus, associated with a heel attaching'machine in which the top-lift is situated with'the side to be pasted turned upwardly; r Fig. 2 is a broken side elevation of the same apparatus, looking from the left in Fig. 1; I r

Fig. 3 is a side elevation, illustrating the apparatus in use with an attaching machine in-which the inner surface of the top-lift is turned downwardly; and i 1 41- is a perspective view illustrating the'applying memberand its more closely associated element-s on a larger scale than the preceding figures.

At 10 appears a portion of the supporting frame of such a heeLattaching machine as that previously mentioned, there being supported upon this frame the customary die-block 12. Pivoted at 14 in proximity to the die-block for movement above it, as illustrated in Figs. 1 and 2 of the drawing, and beneath it, as appears in Fig. 3, is a swing-plate '16, having the usual heel-clamp 18 and tozp-lift-clamp 20. Mounted adjacent to the swing-plate is a paste-holder, shown as in the form of a receptacle 22 situated preferably just in front and somewhat at one side of the top-lift-clamp 'when the swing-plate is in the heel-attaching position. It is preferably maintained adjustably in the desired relation to the top-lift-clamp by an arm 24, perforated and divided to permit it to be secured by a screw 25 at the desired height and angle upon a vertical spindle 26 rising or depending from a bracket 28 projecting from one-side of the frame. receptacle upon a spindle 30 is an auxiliary paste-holding or presenting member 32 having a body of absorbent material, as felt. This presenting member is shown as hexagonal in section, thus having a plurality of surfaces arranged to successively present the paste carried thereby opposite a somewhat contracted opening in-a cover 34' hinged t 36 upon the receptacle Rotatable in the end walls of the Pivoted at 38 at the rear of the receptacle is a movable supporting or transferring arm 40, which, ashere illustrated, is angular in form, extending in its normal or inactive position first downwardly from the pivotal point below the top of the receptacle, and then upwardly above said receptacle,being arranged to receive at its forward extremity a paste-applying member 42. The applying member is preferably furnished by a bellcrank lever 44, having at the lower end of its normally downwardly projecting arm a yieldable. applying surface 46 for contact with the paste-holding member 32 and with the work.,? The lever 44 is fulcrumed at 48 upon one arm of a bell-crank carrier lever 50, the other arm of which has a laterally extending-hub 52 rotatable about a stud 54'fixed" upon the supporting arm. Preferably, this'arm is slotted at 56t'o receive the stud 54, which may be secured in different positions .by a nut 58 operating upon a threaded end of the stud, and which draws a collar 60 fast-upon said stud against the side of the arm. By means of this connection, the carrier and therefore the applying member may be changed in their relation to the holder and to the Work. Fixed at the angle of the bell-crank lever 50 is a stud 62, upon which is mounted to turn a link 64' At the lower end of the link is a short lateral hub 66, through which extends a stud 68 passing through a slot 70 lying along the arm of the bell-crank lever 44 opposite that bearing the applying surface. Pivoted upon the stud 68 outside the lever 44 is an operating member or handle'72, in which is a longitudinal slot 74 to receive the end of the stud 54. Arranged to turn at 7 6 on the arm 40 near its pivotal point is a pawl 78 adapted to engage a series of pins 80, corresponding in number to the presenting sides of the member 32 andsituated about a wheel 82, this wheel being fast upon the spindle 30 outside the receptacle. A pin 84, projecting from the side of the receptacle, co-operates with the upper face'of the pawl to maintain it in engagement with the pins 80 as it is moved in the oscillation of the arm 40 and to limit the arm movement; i l

Considering first the pastin of a toplift T-held with its inner surface up (Figs. 1 and 2), the receptacle being supplied with paste Pso that the member 32 is immersed in it, the applying surface 4-6 normally rest-s uponone of the faces of said member, and receives therefrom a coating of the paste. In using the apparatus, the operator or operators' helper grasps the handle 72 and" swings the arm 40 about its pivotby force exertedupwardly and rearwardly, until the applying member passes a vertical through the arm pi-vot,when it is allowed to descend, and theapplying surface is forced against the toplift, This last-mentioned position is as appears in dotted lines in Fig. 2. The application having been thus made, the applying member is returned to its initial position, a lifting pull now being exertedupon the handle and the surface 46 allowed to drop upon the presenting member. It at this time comes into contact with the succeeding face bearing a fresh supply of paste, since during the rearward movement of the arm 40 the pawl 78 engaged one of the pins 80, turning the wheel 82 through such an angle asto produce this result. If, on the otherhand, the application to be madeto the top-lift positioned as in Fig. 3, the operator, in addition to lifting upon the handle- 72, exerts pressure upon it longitudinally,- or in the direction of the stud 68, with a tendency to anti-clockwise rotation (Fig. 2) about the stud 54. Since the stud 68 is limited by the link 64 to move through theously force is exerted as before to carry the supporting arm about its pivot, and when the surface 46 reaches itshighest point, it

may be pressed'by movement of the carrier lever 50 about the stud 54 against the downwardly turned top-lift. If the reversal ofthe applying member is not accomplished during its travel, when the parts reach the position illustrated in dotted lines in Fig. 2, at the limit of rearward'movement of the arm 40 about the center 38 determined by contact of an upturned end 85 of the pawl 78 with the pin 84, continued pressure upon the handle with a downward tendency of its inner end will positively turn the applying member so that its surface 46 is as appears in Fig. 8. In the return of the arm 40 to its initial position, the pull upon the handle rotates the bell-crank lever 44 upon its ful';

crum in the opposite direction, so that the surface 46 is caused to face down and return to contact with the presenting member" 32. The rotation of the lever 44 in this direction may be limited by the contact of the stud 68 with the end of the slot 70. In the pasting of the upturned surface previously described, there was lacking the longitudi nally applied force upon the handle to cause travel of-the stud 68 through the slot 70 and the movement of the slot 74 along the stud 5 4, which produces the reversal of the applying surface. But, if the operator finds any difficulty in manipulating the applyingi member without reversal, it may be locked in its downward applying position by a pin inserted through alined openings 86 in the link 64 and the lever 50.
